It feels like playing the classic Three Kingdoms. It feels very similar to the version of the web game of the Three Kingdoms.
It's multiplayer, but it's kind of like a single game. First off, the game demonstrates the basic strategic playstyle. You can strategically expand your territory through your own strategy and longevity, and you can play the game in your spare time without charging enough, unlike the general P2W SLG. So there is no need to stress.
However, the game doesn't seem to have any special features from the web game. If you are a fan of the Three Kingdoms game and strategy SLG, this is the game I recommend.
